Uni-ball UM-153 Signo Broad Metallic Gel Pens are a 1.0mm rollerball pen with a 0.6mm line width. The opaque, water-proof gel ink is light-fast and acid free.
They come in a range of sparkly metallic colours and a very opaque white. They work really well on black, dark and coloured paper, as well as white.
The White Uni-ball Signo Pen is also a popular choice with artists for adding highlights to their drawings and paintings and for making corrections.
These pens have a comfortable rubber grip and are a must have pen for sketchbooks with black paper and all your arts and crafts projects.
